IMPROVEMENT IN WATER-ELEVATORS.

Specification forming part of Letters Patent No. 35,] I3, dated April 29, ISG?.

To all whom it may concern:

Be it knowu'that I, IsAAc SHEEwooD, of Unadilla, in the county of Otsego and State of New York, have invented a certain new and useful improvement in the construction of apparatus for drawing water, by means of which a rotary is converted into a reciprocating movement for the purpose of alternately letting down and lifting up abucket orbuckets; and I do hereby declare that the following is a full and true description thereof, reference being had to the accompanying drawings and the letters and figures of reference marked thereon.

Figure l represents afront elevation of the apparatus. Fig. 2 is a plan of the same. Figs. 3, 4, 5, and 6 are views of the gearing in different positions.

A and A2 are spools respectively attached to the shafts B and B2, resting on bearingsin the frame C C and geared together by the cogwheels D and D2, having an equal number of cogs and therefore producing a uniform motion in opposite directions. The wheels D and D2liein different, though parallel, planes of motion, but overlap each others faces suficiently to iirmly and constantly interlock, as shown in Fig. 2 and also in Figs. et, 5,and (i.

Motion is communicated to the spools by the toothed wheel E upon the shaft F, having its bearings attached to and elevated above the frame C C and rotated by a crank or other driving gear. This wheel E, with its shaft F, has a lateral sliding movement in these bearings, by means of which it may be made alternately to gear with either I) or D2, so as to I reverse their motion, or may be made to gear with both at the same time in such a way as to lock them and prevent a motion of either. As each bucket approaches the termination of its upper movement it strikes the arm G or G2 of the lever H, pivot-ed at I to bearings upon the frame C C. The upper arm of the lever H grasps the wheel E between the forks K and K2, and by means of the elbow-joint at I the motion communicated by the bucket striking the lever G or G2 is converted into a lateral sliding movement of the wheel E and its shaft F, the object or eiect of which is to cause the wheel E to gear both with D and D2 at the same time in such a way as to lock them and prevent a motion of either. In this way, where two buckets are used one is held stationary while being emptied and the other is kept underwater and permitted to fill.

The advantages of my invention are that I am enabled to raise and lower the buckets alternately by a uniform mot-ion of the shaft F in one direction; that I am enabled to make the spools A and A2 and also the gearingwheels of diierent sizes, as I may wish to obtain different degrees of power or velocity, or as convenience may dictate; that the lateral sliding movement of the shaft F with the wheel E may be communicated by the strike of each bucket as it approaches the termination of its upward journey, and that by causing the wheel E to gear with both D and D2 at the same time the latter may be locked and the motion of either checked and the bucket and its contents held at rest without ratchet or pawl.

I claim as my invention and desire to secure by Letters Patentl. A water-elevator having in combination the wheels D and D2 and E, constructed and operating substantially as above described.

In combination therewith the double-acting lever G and G2, H K K2, constructed and operating substantially as hereinbefore described.
